Question

I have a app with images and once the user presses the image a sound clip will be played. Once i reach the last image (25), which does not have a sound clip, if i press that the app gets closed automatically how can i prevent this.

For example i need to play C01.mp3 once the user Click 01.Png ( Note all my images are also kept in a image array ) Basically I have 25.png this is just a advertisement to my site so it would not have a sound clip but once i click that image the applicaiton gets close automatically. Need help to sort this out.

replace

for(NSString *soundName in soundNames)
{

with

for(int i = 0 ; i < soundNames.count-1 ; i++)
{
   NSString *soundName = [soundNames objectAtIndex:i];
   //rest of the code same

This will run the loop till 23 indexes of your 24 indexes array..
